Free tool crib software for linux

MIME-tool is a little mime encoding tool I slapped together when I needed something on a production box at work (productions = no C development environment, only the ancient K&R compiler required for god-knows-what sys-admin task).
The resulting program will compile happilly on both the crippled C compilers bundled with some commercial *nix distributions, and on full ANSI/ISO C compilers like gcc.
I wrote this program when I needed a tool to construct MIME encoded emails with file attachments in job scripts on a production box. Being a production box it didnt have any development tools installed. However, the box DID have a K&R C compiler that appears to be necessary for some administrative task or another (configuring the kernel?). If you tried to compile even fairly simple ANSI/ISO C source the compiler bitched and moaned about all the stuff it didnt support, which will stop most folk (at least those who dont know anything about the history of the C programming language) from building their own binaries.
Since Im old enough to actually have written C code back before we had the ANSI/ISO standard and all the accompanying niceties, I was not stymied by a the lack of ANSI/ISO support. Its really not all that hard to write K&R compliant code, so long as you dont need the compiler to check your function calls for you. For a program this small, however, thats not much of a concern.
Since the program is meant to be compiled on systems with minimal support (there is no telling what unrestrained IT staff will decide must be removed in the interest of system security) I didnt bother to include a makefile. On every system I have tried, however, the program compiled with the simple incantation
cc -o mime mime.c
but your selected target system may require extra special magics.
The program supports the basic MIME standard: The caller can select the content type (application/octet-stream, text/plain, or user specified), content type encoding (7bit, 8bit, binary, base64 or auto-detected) and the boundry string (defaults to "=_MIME_CONTENT_BREAK_="). Further, the caller may specify the e-mail subject, to address, from address, carbon copy address and text for a prolog and epilog. The content type and encoding may be specified separately for each attached file.
The programs calling format is:
mime [-dDvV] [-S subject] [-F from-address] [-T to-address]
[-C carbon-copy address] [-P prolog-text] [-E epiplogue-text]
[-B boundry] {[-78abqux] [-t content-type] filename}
-d low detail debugging
-D high detail debugging
-v verbose messages
-V very verbose messages
-7 7-bit ASCII encoding
-8 8-bit ASCII encoding
-a application/octet-stream content type
-b binary encoding
-q quoted-printable encoding
-t text/plain content type
-u unknown encoding, auto-detect
-x base64 encoding
Theres really not much to this program. Once you know how the MIME messages are constructed you could do most of it manually (except for the base64 encoding, which would require a program like this), but if there are any problems with it, I would like to know about them.
Enhancements:
- A typo in the online help message was fixed.
- A known bugs section was added to the manpage.
- Proper quoting and folding were added to the filename header.

graph-tool project is a program to help with statistical analysis of graphs.
Main features:
- support for directed and undirected graphs
- support for arbitrary vertex or edge properties
- generic filtering of edges and vertices
- several statistical measurements:
- degree (or scalar property) histogram
- vertex-vertex degree (or scalar property) correlation
- average nearest neighbours degree (or scalar property)
- vertex-edge-vertex correlation
- clustering coefficients
- assortativity coefficient
- average distance
- component statistics
- generation of random graphs with arbitrary degree distribution and degree correlation
- graph history measurement based on filtering
- support for graphml and dot file formats
The core algorithms are written in C++, making use of the Boost Graph Library, and template metaprogramming techniques, with performace in mind. The command line interface and other outlying code are written in python.

CSE-Tool allows you to easily deploy a Google Custom Search Engine by copying and pasting a few lines of code provided to you by Google.

CSE-Tool doesnt require a database.

Sudoku Tool is a sudoku game that helps you to solve sudoku puzzles. Sudoku Tool can generate puzzles randomly or puzzles can be entered manually.

Some of the features include random puzzle generation, pencil marks, and the ability to save games.

Manual Setup:

The game starts in initialization mode. In this mode, you are setting up the a puzzle that you got from a newspaper, online, ... You are manually setting up the puzzle.

To select a location, click a square with the left mouse button and type in the number you want to place 1-9, or 0 or space to remove a value you placed there previously. You can also change other values by simply typing a new number.

When you have the puzzle set up the way you want, click the Start Game button to start playing.

Random Game:

To have a game randomly generated for you, click the Setup New Game button. A new window pops up asking you to select either "Manual" or "Random". Select "random" and a new game will appear.

To build, use:

make -f Makefile.[system]

Need help avoiding phishing and spoofing attacks? Petname Tool can help you avoid online fraud by clearly distinguishing your online relationships.

Using the petname tool, you can save a reminder note about a relationship you have with a secure site. The petname tool will then automatically display this reminder note every time you visit the site.

After following a hyperlink, you need only check that the expected reminder note is being displayed. If so, you can be sure you are using the same site you have in the past.

GTK ACX Tool provides a tool that displays the status of the ACX100 driver.

The GTK ACX Tool displays the status of the Texas Instruments (TI) ACX100 IEEE 802.11 driver. This tool could be used just with driver developed by wlan.kewl.org Project on FreeBSD 5.2 and later versions.

It uses GTK+ and GtkDatabox (a GTK+ widget for fast data display). The ACX driver can be installed via the ports collection.
